Abstract:
Structure and composition of graphite-like carbon films obtained by pulsed laser deposition in an inert gas atmosphere using sacrificial carbon tapes are investigated. The deposited films are studied using X-ray diffraction, photoelectron spectroscopy, and Raman spectroscopy. X-ray diffraction analysis shows that the obtained films have a structure characteristic of turbostratic carbon and reduced graphene oxide. Analysis of the photoelectron spectra allows us to draw a conclusion about the significant decrease of oxygen and hydrogen content in the films compared to the target material, as well as significant diminution of the content of the $sp^{3}$-phase. Using Raman spectroscopy, it is shown that carbon films have characteristic features of graphite/graphene and a two-dimensional (turbostratic) structure with characteristic sizes of $sp^{2}$-crystallites of the order of 15–18 nm depending on the density of laser pulse energy.
